I got the heat panel. It took a day sitting next to his cage, and when I attached it next to the perch he usually sleeps on, I put him in the cage and he was looking at it all funny while he was eating. Then I covered him for the night and when I came down in the morning and uncovered him, he was next to it. He acted the same for the next few days with it, but every time in the morning he was next to it. He is still getting use to it. It is close to the bars, but luckily he has not tried to touch it. He is good about not trying to destroy things. This was the free cage mount, but after I ordered and got the instructions they do make a mount that sets the panel farther back.
